One of the most significant challenges facing mankind in the
twenty-first century is the development of a sustainable global
economy. Within the scientific community, this calls for the
development of processes and technologies that will allow the
sustainable production of materials from renewable natural
resources. Plant material, in particular lignin, is one such
resource. During the annual production of about 100 million metric
tons of chemical wood pulps worldwide, approximately 45 and 2
million metric tons/year of kraft lignin and lignosulfonates,
respectively, are also generated. Although lignosulfonates have
found many applications outside the pulp and paper industry, the
majority of kraft lignin is being used internally as a low-grade
fuel for the kraft pulping operation. A surplus of kraft lignin
will become available as kraft mills increase their pulp production
without expanding the capacity of their recovery boilers that
utilize lignin as a fuel. There is a tremendous opportunity and an
enormous economic incentive to find better uses of kraft lignin,
lignosulfonates and other industriallignins. The pulp and paper
industry not only produces an enormous amount of lignins as by
products of chemical wood pulps, but it also utilizes about 10
million metric tons of lignin per year as a component of mechanical
wood pulps and papers. Mechanical wood pulps, produced in a yield
of 90-98% with the retention of lignin, are mainly used to make
low-quality, non-permanent papers such as newsprint and telephone
directories because of the light-induced photooxidation of lignin
and the yellowing of the papers.
